OSGi - modularity layer for Java platform.
The OSGi bundle as a unit of modularization that is comprised of Java classes and other resources which together can provide functions to end users.
In other words it is a Java Archive File that contains Java code, resources, and a manifest that describes the bundle and it's dependencies.
Each bundle is a tightly coupled, dynamically loadable collection of classes, jars, and configuration files that explicitly declare their external dependencies (if any).
The bundle is the unit of deployment for an application.
